With the Ravens improving to 3-0 for the first time since 2009 with a 19-17 victory at Jacksonville on Sunday, I’ve offered a dozen thoughts, each in 50 words or less:

1. Much praise has already been offered to the fourth-quarter performance of the Ravens defense, but the numbers were just sensational. Jacksonville ran 17 plays for four net yards while Baltimore collected four sacks, two interceptions, and two batted passes. That’s how you finish games.

2. Mentioning last week how methodical the Jacksonville defense has forced the Ravens to be, Joe Flacco threw 40 times with only completions of 20 or more yards. The Jaguars used deep safeties and an underwhelming running game didn’t help matters, but the Ravens must take more vertical shots.

3. Speaking of the running game, many want Terrance West to receive the bulk of the carries, but the Ravens don’t trust him as much in pass protection, which can’t be overlooked in a pass-happy offense. Still, you hope rookie Kenneth Dixon can eventually give a sputtering ground attack a spark.

4. John Harbaugh quipped that rookie linebacker Kamalei Correa needs extra work on the JUGS machine after dropping an interception that could have been a touchdown, but it was good to see the second-rounder make on impact with his first defensive action. Now he needs to build on that.

5. I had concerns after his Week 1 performance in which he had only 19 receiving yards on eight targets, but Steve Smith looked like his old self against Jacksonville, gaining yards after the catch and making four receptions in the fourth quarter. Maybe Jalen Ramsey did him a favor?

6. Many have criticized Shareece Wright after two rough games in a row, but shouldn’t Jimmy Smith be traveling with a receiver as talented as Jacksonville’s Allen Robinson? Wright does need to be better in coverage, but the Ravens gave Smith a big contract for those types of matchups.

7. Just 8-for-19 on tries from at least 50 yards in the previous two seasons, Justin Tucker is living up to a fat contract by nailing all three tries from that range so far, including the game-winning 54-yarder in Jacksonville. He’s easy to take for granted, but he shouldn’t be.

8. It’s ironic that Flacco’s franchise record of 21 consecutive completions ended on his best throw of the day that was dropped in the end zone by Mike Wallace. It wasn’t the best day for the veteran receiver or Breshad Perriman, who also dropped a couple of passes.

9. One of the big differences in the defense has been the improved pass coverage from the inside linebackers. C.J. Mosley and Zach Orr are getting better depth in their drops, and both came away with interceptions on Sunday.

10. Brent Urban gave the Ravens’ their 10th blocked kick since 2014, which proved to be the difference in the game. Special teams can be a great equalizer in overcoming deficiencies on offense or defense, and blocks have swung momentum two weeks in a row.

11. Alex Lewis did leave Sunday’s game with a concussion, but the Ravens listingthe same seven inactives for the third straight week illustrates how healthy they’ve remained since the start of the regular season. They need Elvis Dumervil and Dixon to return, but they should feel fortunate otherwise.

12. Harbaugh says he isn’t superstitious, but his gray T-shirt worn on the sideline two weeks in a row will apparently be donned again against Oakland. It’s a more relaxed look for the ninth-year coach than we’re used to seeing, and it reminds a bit of Bill Belichick with the hoodie.
